Prepare the switch. Keep a way back.
Choose two catalog configurations and build a review checklist before switching a model integration.
This planner does not migrate data, rotate keys or call a model. Website catalog IDs are not provider API model IDs; obtain the exact execution identifier from the intended provider.
Preserve the current baseline
Record the deployed configuration, prompt version, access controls and acceptance tests. Retain a rollback path and a representative non-sensitive evaluation set before changing an integration.
Verify actual API compatibility
Check the target provider's execution identifier, request format, tools, streaming, error handling and supported limits. A shared provider name or an API-shaped response does not prove compatibility.
Review cost without assuming quality
Use separate input and output prices with the same volume assumptions. Keep unknown rates and capacity conflicts visible. Include engineering and test costs in a transition scenario; lower token spending is not proof of better task results.
Test, observe and retain rollback
Run acceptance and regression checks, inspect failures, then review a bounded release. Record the exact deployed version and recheck behavior before broadening traffic. This website prepares a checklist; it does not perform that release.
